Has your Gmail been hacked? Here’s how to tell and how to recover your account

With over 1.8 billion monthly Gmail users, Google blocks nearly 15 billion unwanted messages every day, including spam, phishing, and malware. But even if you go out of your way to secure your Gmail with a strong password and 2FA, attackers might still find a way to bypass your precautions.

So, how do you know if your Gmail has been hacked? And what can you do about it?

Can someone hack your Gmail and your Google account?

The short answer is “yes.” No online account is ever fully immune to cyberattacks.

Hackers can gain access to your Gmail through stolen passwords, phishing, session cookie theft, or malware in your inbox. All are ways that don’t require attackers to brute-force their way through Google’s strong defenses. Even worse, because your inbox can be used to reset passwords for other accounts and services, a compromised Gmail can also expose your other accounts.

A “Gmail breach” warning doesn’t typically mean that Google itself was hacked. For example, in October 2025, Have I Been Pwned reported on a database of stolen credentials compiled by Synthient, containing over 180 million email addresses and passwords gathered through infostealers. Soon after, in January 2026, researcher Jeremiah Fowler discovered a publicly accessible database containing around 150 million credentials, 48 million of which were Google logins.

In both cases, Google denied a direct breach of their servers, blaming user devices infected with third-party malware as the culprit. More recently, frequent reports mention the rise of AI phishing, in which emails and voice messages are made by AI and designed to sound like Google support agents. People are falling for it.

Why changing your password alone may not be enough

A leaked or stolen password isn’t the only way someone can gain access to your Gmail. A stolen session cookie, for example, lets an attacker remain authenticated without re-entering your password or having to verify using a 2FA code.

That’s because Google doesn’t automatically invalidate existing sessions when you change your password. You need to do it manually: Open your Google Account, then click on “Security & sign-in.” Under “Your devices,” click on “Manage all devices,” where you will find the option to sign out of every unfamiliar session.

What happens if someone hacks your Gmail, and why do criminals do it?

There are different methods hackers use to infiltrate Gmail accounts, including the use of already breached accounts familiar to victims, phishing attacks where you click on malicious links, and malicious apps that steal cookies along with your hacked Gmail credentials.

The consequences of a hack will depend on the methods used by the attackers and on whether they are looking to simply extort you or take it further. Once criminals take over your hacked Gmail, they will lock you out and search for sensitive information and financial data. 

This means facing financial and personal consequences. Additionally, the hacker will try to compromise any other accounts linked to your Gmail. Any information they get can be used for identity theft, fraud, blackmail, and more. 

Cybercriminals may also use your Gmail account to carry out illegal attacks on the people you know.

Once a cybercriminal hacks your Gmail password and Google account, they can:  

• Change passwords 
• Change verification and notification settings
• Send spam emails
• Steal your data
• Breach your bank accounts or digital wallets 
• Sell your personal information on the dark web
• Extort you
• Shut down the account 
• Remotely delete devices linked to your Google account
• Steal passwords to other websites
• Hack your social media like Snapchat, Facebook, or TikTok

But why would they hack a Gmail account? What are their motives for Google account to be hacked? Why go to all that trouble? Some motives are known only to them, but here are some possibilities:

1. It’s profitable – at the end of the day, everything comes down to money. If something can be turned into money, a criminal is going to naturally gravitate to it. A Gmail account is quite often the gateway to other online accounts such as banking, PayPal, crypto wallets, and so on. Having control of your Gmail address allows attackers to reset the passwords.
2. They can impersonate you – by using your Gmail, they can send emails to your contacts and pretend to be you. Your contacts may be unaware your account has been hacked and proceed to divulge sensitive information.
3. They can sell the account – there’s a demand on the Dark Web for Gmail accounts, especially ones with rare names. An account is also in demand for all the reasons listed above.
4. Work accounts are even more wanted – if they manage to take over your work Gmail account, they can fake invoices, redirect payments to their own accounts, grab sensitive work documents, and more.
5. They can blackmail you – sensitive pictures? Compromising personal emails? These can be used for blackmail.
6. Use your Gmail as a spam machine – spam is a big money maker for hackers and cybercriminals. Taking over your Gmail gives them one more account to use.
7. They do it for kicks – sometimes, people just do things for the bragging rights. They like to tear things down. Sometimes, they just have no motive.

A hacked Gmail exposes more than your inbox. In 2024, the FBI recorded $16.6 billion in losses due to cybercrime, while Mandiant found that stolen credentials accounted for 16% of infection methods the same year.

Google’s built-in security measures for Gmail

Google doesn’t make it easy for hackers to break into accounts, but no matter how many security fallbacks are put in place, it all comes down to the user and how they choose to respond to those hacking attacks.

Nevertheless, here is how Google is attempting to repel Gmail invaders.

1. 2-factor authentication – by enabling this, you’re making it much harder for a hacker. Don’t have the codes sent to your phone number, as those could be intercepted. Instead, use an authentication app on your phone, such as Google Authenticator.
2. Gmail’s filters are top-notch – spam (such as phishing emails) is a constant problem, but Gmail claims that their filters manage to catch about 99% of offenders. If any messages get through, Gmail will label them as “dangerous” and let you make up your own mind.
3. IP checking – if you usually log in from a certain IP address, and suddenly, a login attempt is made at another IP address, Google will temporarily block it while they ask you to verify your identity with a 2FA code or a password. This is most likely to happen if you’re using a foreign VPN server.
4. HTTPS links – all Gmail processes are now done via encrypted HTTPS links, preventing man-in-the-middle attacks.
5. Recovery reminders – now and then, Google will remind you to add a recovery email address and/or a recovery mobile number, in case you get locked out of the account.
6. Passkey support – Instead of a password, passkeys let you sign in using your fingerprint, face scan, or device PIN code, making you more resistant to leaks and phishing.

How to tell if your Gmail has been hacked

Google explains that someone else might be using your Gmail without permission if you notice unfamiliar activity in any of your Google products. A quick way of knowing if another device is using your Gmail account is to check My Account > Security > Your Devices. This section can show you details about all the devices that have logged into your account in the past 28 days. 

On the other hand, there are several other signs that serve as clear indicators that your Gmail has been hacked.

1. You entered your Gmail credentials on a phishing page

If you followed a suspicious link to a fake Gmail login page, it’s safe to assume that it was stolen, and you need to immediately change it and log out of any unfamiliar sessions. To avoid falling for phishing emails, copy and paste suspicious messages into Moonlock’s Scam Detector to check them for telltale signs of a phishing scheme. Start a free 7-day trial to protect your Mac from scams, malware, and more.

2. Your password has been changed

If you try to log in to your account only to discover that your password is not working, it either means you forgot it, or someone has hacked your account. Most Gmail hackers seek to shut you off from accessing your account and will change the password. But some criminals prefer that their victims not know their accounts have been hacked, so they will leave the password unchanged. 

If your password is changed, take immediate action and start the Gmail recovery process, as explained below. 

3. Your Inbox and Sent folder look off

If the first thing you notice when you access your inbox is that something is off, you should trust your instincts and seek to identify what’s wrong. 

Hackers will often open unread emails, send spam from hacked accounts, and email friends and contacts to further continue scamming and hacking. You might also notice emails from Gmail or other sites notifying you about security and password changes. This is a clear indication of a manipulated account.

4. Your Settings have been changed

Hackers may change the settings of your Gmail or Google account. Once they gain access, they can forward your emails to another account and change the security questions, 2FAs, and recovery emails.

In other words, it’s not enough to simply check your password after noticing suspicious activity. Hackers may add phone and recovery emails to easily gain access in case you recover the account. 

If your Gmail starts acting strangely:

• Check your Security settings for unfamiliar devices or recovery details.
• Review your Gmail Settings.
• Navigate to “See all settings” and look for unknown forwarding addresses, filters, POP/IMAP access, and signatures.
• Remove anything unfamiliar or suspicious.

5. You are getting strange security notifications

Often Gmail accounts are linked to cellphones or other emails. If you are getting unusual notifications about login attempts or changes in security settings, it is a red flag that someone is trying to hack your email — or has already hacked it. 

Additionally, if your friends, family, or contacts tell you that they have received strange messages or notifications, or are receiving emails from you that you didn’t send, take immediate action to secure your Gmail account.

6. Your other services have been hacked

One of the main reasons cybercriminals hack into a Gmail account is to gain the resources to set new passwords to access other sites, including bank accounts, e-wallets, crypto sites, or work systems. They might also be hacking your Gmail to get to Google documents like online spreadsheets, or to use other Google products linked to your account. 

Always be vigilant about any emails from Gmail or other accounts related to password changes you did not request or other security notifications. Additionally, remember that if one of your Google services has been hacked, there is a chance the hacker first hacked your Gmail to access the site. 

7. Unknown email filters or forwarding rules

Attackers can remain hidden even after gaining access to your Gmail, adding filters that hide security alerts or forward a copy of your messages to them. Click on the gear icon in the top-right corner of your Gmail account, then select “See all settings.” Under “Filters and Blocked Addresses” and “Forwarding and POP/IMAP,” delete any unfamiliar filters or forwarding addresses.

8. Your display name or email signature has been changed

After gaining access, hackers can alter your sender name or signature to spread scams or redirect replies. To check whether that’s the case, go to Settings and choose “See all settings.” Click on “Accounts and Import,” then “Send mail as.”

Restore your original information and remove any unfamiliar sending addresses.

9. Bounce-back emails from accounts you never emailed

Delivery failure messages for emails you’ve never sent might indicate that someone else is using your account or spoofing your address. Check your Sent and Trash folders for undelivered email, as well as Gmail’s bottom-right Details panel. If you find any, change your password and sign out of unfamiliar sessions.

How to find out who hacked your Gmail account

You can use Gmail’s built-in activity log to find the IP address and rough location of the unauthorized session. It also typically includes information on the device used to access your account and when exactly the session was started.

Here’s how to find out who hacked your Gmail account:

1. Open Gmail on desktop, then scroll to the bottom of your inbox.
2. Next to “Last account activity,” click “Details.”
3. In the pop-up window, review the recent sessions based on access type, date, time, IP address, and general location.
4. Copy the suspicious IP address into an online IP Lookup tool to estimate the location.
5. Compare the results with your own device use and recent travel or VPN usage.

Keep in mind that this information rarely allows you to identify the individual. Not to mention, they’re likely using a VPN or proxy to further mask their real location, so you might not even get the correct answer.

If you’ve experienced serious damage from a compromised Gmail address, whether it’s to your finances or in the workplace, your best option is to preserve evidence with as many screenshots as possible and take them to a reputable digital forensics professional.

How to recover your hacked Gmail: Step by step

Act quickly to improve your chances of successfully recovering your hacked Gmail.

Start from a device, browser, and Wi-Fi network that Google already recognizes and is associated with your account. Avoid using public Wi-Fi, a VPN, or a public computer because Google uses all of these familiar signs to verify ownership of the account. Here’s what to do:

1. If you’re completely locked out, visit Google Account Recovery and answer the security questions accurately.
2. If you still have access, go to “Settings,” “Security & sign-in”, then “Password,” and reset your password.
3. Under “Security & sign-in,” “Recovery phone,” and “Recovery email,” remove any details you don’t recognize.
4. Sign out of all unknown sessions and devices.
5. Visit myaccount.google.com/security-checkup to review recovery options and third-party access.
6. Enable 2FA or a passkey to secure your account for good.
7. Run a malware scan with the Moonlock antivirus to eliminate any potential infostealer.

Can I contact Google about a hacked account?

“Someone hacked my Gmail!” If this is you, Google security experts are available to assist you and other users who report a hacked Gmail account.

It is possible to contact Google security experts about your Gmail hacked account through various channels, although they usually prioritize paying Google Workspace customers.

As mentioned above, it is essential to first attempt a password reset and an account recovery. If those steps to recover your account fail, then the next possible step is to contact Gmail Community experts.

To contact Gmail Community Experts: 

1. Go to Google Account Help and click the ? icon at the top-right of the page.
2. When the side box opens up, click “Secure a hacked or compromised Google Account.”
3. You will see options such as account recovery and password resets. If you’ve tried and failed with all that, scroll to the bottom of the page and click “Need more help? / Ask the Help Community.”
4. A new page will load where you can ask your question and contact an expert.

Those who use Google accounts through work or school and are Google Workspace administrators can contact Google directly for support. 

To contact support for Google Workspace:   

1. Sign in to your Google Admin console using an administrator account email. 
2. At the top right of the Admin console, click the ? icon.
3. When the sidebar window opens, a chat widget will start up, where you can explain your problem and ask for help.

It’s worth keeping these steps in mind, because Google accounts being hacked are big business.

How to recover a hacked Google account without a password

Things get a bit more complicated if you are late to the show and the hacker has already changed the password. However, just because your password has been changed, it doesn’t mean you will lose access or control of your Gmail account. 

Remember: The sooner you take action, the better. Wait too long, and hackers will change all methods you have to verify that the account is yours and lock you out.   

To start the account recovery process, go to the recovery page and follow these steps:

1. Go to Google’s account recovery page at accounts.google.com/signin/recovery or open Google’s sign-in page, then click on “Forgot password?”
2. Enter the most recent password.
3. Google will then prompt you to go through multiple verification methods, such as a recovery email, phone, backup code, or recognized device. Choose the best option for you.
4. If none are working, select “Try another way” and continue answering your security questions.
5. Once verified, you’ll be able to create a new password.

To improve your chances of a successful recovery, use a familiar device, browser, Wi-Fi network, and location when attempting it. Answer all questions to the best of your ability and avoid skipping any. After the recovery:

1. Set up 2FA
2. Update your recovery details
3. Go through Google’s Security Checkup.

Keep the following tips in mind for a successful recovery process:

• Answer the questions as best you can.
• Don’t skip any questions. Even when not sure, take your best guess. 
• Complete the recovery on a device linked to your account that Google will recognize. 
• Do it in a location that Google will recognize and associate with the account (for example, your home or work). 
• Be exact with passwords and security question answers. A typo can mean the difference between gaining access or not. 
• When asked to enter an email address, use one already linked to your account that you can access.

Once you regain access to your account, you should change your password and check your 2FA and your security settings.

How can I recover my Gmail password without my phone number and email?

If you do not have your phone and have no access to your email, the only way to recover your Google account is by following the steps listed above for Account Recovery. There is no other way. 

There are countless services online that promise customers they can recover their Gmail account and often ask you for passwords and other details. However, these services are scams. Do not engage with them, as no third party can recover a Gmail account that belongs to you. Again, this can only be done through the Account Recovery process detailed above. 

To summarize the Account Recovery steps:

1. Visit the Google Account Recovery Page.
2. Type in your Gmail username or ID.
3. Choose “Try Another Way to Sign In”.
4. Here you can choose different options: Verification Using Another Device, Using Backup Codes, using secondary emails, phone calls, etc. The options you see at this step will depend on what security settings you have enabled in your Google account.  
5. Wait for the Password Reset Link.
6. Reset your password.

How to delete your hacked Gmail account

The only way to delete a Gmail account is to have access to the account. So if a hacker has shut you out, you will have to go through the recovery process to prove to Google that the account belongs to you. Once you do that, you can delete the account. 

Deleting your Gmail account will not delete your Google account, nor will this delete other Google products. However, it is an option for those who want to delete a compromised email address. Remember, your emails and mail settings will be lost, and the email address will no longer be available to use. 

To delete your Gmail account:

1. Before deleting your Gmail service, download your data.
2. Go to your Google Account. On the left menu, click “Data and privacy.”
3. Scroll down to “Data from apps and services you use.”
4. Under “Download or delete your data,” click “Delete a Google service.” You may need to sign in.
5. Find Gmail and click “Delete Icon.”
6. Enter an existing email address to sign in and click “Send verification email.” (This email can’t be sent to a Gmail address.)
7. Until you verify the new email address, Google won’t delete your Gmail address.

Additionally, you have the option to delete your entire Google account, including Gmail. If you choose to do so, download your data first (see the steps above). It is also recommended that if you use your Gmail account to recover passwords or as a login credential for other services like your bank, work, or school sites, change the email on those first.

To delete your Google account:

1. Go to the “Data and Privacy section” of your Google Account.
2. Scroll to “Your data and privacy options.”
3. Select “More options” and then “Delete your Google Account.”
4. Follow the instructions to delete your account.

What else can you do if your Gmail was hacked?

If you are hacked, time is of the essence to go on the offensive. You only have a small window of time to recover a hacked Google account before the attacker completely locks you out.

1. Change your password – if you think someone else is inside the account, change the password immediately and lock them out.
2. Change Google account settings – again, assuming you still have access to the account, go into your Google account, and remove all sensitive information. Disconnect any third-party apps that have access to your Gmail.
3. Warn your contacts – to stop the hacker successfully impersonating you, warn your contacts to ignore any messages from that email account.
4. Remove any suspicious browser extensions – maybe the hacker got into your account via a browser extension. Remove any extensions you recently installed or any you don’t recognize.
5. Remove unauthorized third-party app access: Navigate to “Google Account,” then “Security.” Under “Third-party connections,” revoke anything unfamiliar.
6. Change Google account settings: Review your recovery details, forwarding info, filters, and delegated access.
7. Warn your contacts: Inform your friends, family, and work contacts to ignore any suspicious messages sent from your account.
8. Use an antivirus software to check your Mac for malware – if the hacker got into your Gmail, there may well be malware on your Mac. Using an antimalware tool such as Moonlock will quickly take care of that. You can get a free trial to try it out for yourself.

If none of the above works, use Google Account Recovery to get it back through security questions.

Common questions about hacked Gmail accounts

Here’s what you need to know about the Gmail recovery process.

Securing your recovered Google account after a hack

Regaining access to your Gmail account is a victory, but the battle isn’t over. Here are some quick tips to fortify your defenses:

• Change your password. This might seem obvious, but use a strong, unique password and enable two-factor authentication (2FA) for an extra layer of security. Change the passwords to any other accounts you have, including banks and financial apps, and enable MFA.
• Set up a passkey. Passkeys are a safer, easier alternative to passwords that use your fingerprint, face scan, or device PIN to log in. To enable a passkey for your Google account, go to the Google passkeys page and follow the steps.
• Review recent activity. Check your sent emails, drafts, and trash for any suspicious activity by the hacker.
• Report the hack to Google. Let Google know about the incident to help them improve their security measures.
• Run Google’s Security Checkup: Visit myaccount.google.com/security-checkup to review linked devices, recent activity, recovery options, and third-party account access.
• Check for recent data breaches: Search your Gmail address on HaveIBeenPwned.com. If it appears, change passwords on every affected account and enable 2FA.

Google goes to great lengths to keep Gmail accounts safe and secure. However, no account is unbreachable. Fortunately, there are many ways to know if your account has been hacked and several processes to recover it safely.
